Metals not running when .vsix installed on air gapped computer

[molotch]

Hi,

I'm trying to get a Scala development environment working on an air gapped computer (offline) with only installation files and a JFROG Artifactory available.

Both vscode and the metals (installed using the .vsix) plugin installs fine. It's just that the metals plugin never activate. It doesn't show up in running extensions, it doesn't react when loading a Scala project and vscodes extension host logs don't show anything related to metals.

Any clues on what might be wrong and what I could try?

Metals is not really suited for offline installation (there is a feature request for that), but you should be able to work around it by specifying coursier mirrors: https://scalameta.org/metals/docs/troubleshooting/proxy.html#mirrors

You should be able to use that alternate Artifactory repo.

@tgodzik well that's what I think as well.
I am just wondering if maven can do it as its working without any issues, what's wrong with metals. Any pointers on what could be wrong?

I would try to use coursier manually to see if it writes anything. It should output all the jars downloaded.

You can also try to run the main class manually and see if there is an issue there.

Thanks a lot @tgodzik I will give it a rey tomorrow morning ( it's 9 pm in Australia).
Just curious if I install coursier manually. How do I get metals to use the "local coursier" instead of the bootstrap version?

[tgodzik]

We search for it on the PATH variable currently. So you would need to make sure it's executable from anywhere

@tgodzik thanks for the help. I managed to make some progress and have now run into a new error for which I have posted another discussion
